Blown instumentation fuses
I purchased a used '97 F-150. The truck is cherry and runs smooth as silk, but, it periodically blows the 5 amp fuse to the instrumentation. No rhyme or reason to when it occurs. I can go weeks or it will happen a couple times a day. I did catch it happen once when I accelerated merging into traffic with my left turn signal on. Other than that I have been unable to observe when it happens. I have tried everything I can think of in an effort to make it happen and it doesn't work. I'm at the end of my wits! Please, Help!
